Ted also cooked the cake; I think from one of the various America’s Test Kitchen books we have. He asked me to make the frosting & frost the cake. One of the things my dad taught me long ago was that putting some sort of jelly or jam between the cake layers is very tasty. So I checked the jelly cabinet and found a jar of orange-elderflower marmalade from Ikea. It made a nice contrast to the basic frosting I made. Ted added a bit of chopped candied tangelo peel he made last month.
